When the Companions heard the details of the Ascension from the Holy Prophet (Sallallahu alaihi wa sallam), they not only safeguarded it in their bosoms, but also conveyed them to others.
The way the Companions would mention the Ascension can be understood with the fact that the Hadith on it have been related by 35 Companions.
The names of those Companions who have related Hadith on the Ascension are being mentioned in the alphabetical order from Subul Ul Huda War Rashad, authoritative book on the life of the Holy Prophet (Sallallahu alaihi wa sallam), from Mawahib Ladunniya, from Sharh Mawahib by Imam Zurqani, from Al Isra Wal Me’raj by Imam Suyuti and from Tafseer Ibn Katheer.
